See Amazon, Others License Adobe Reader Mobile SDK
. This seems to be exactly the same SDK that Sony is using. The difference is that Sony is using all of the SDK, but Amazon is only using part of it.
The problem may be that much of the Kindle's software is in Java, so perhaps integrating the Adobe SDK was harder than Amazon expected. It would probably have been better for Amazon to go with a Java PDF reader, which I'm sure could easily support all that the current reader is doing.
